6.0 GAS FLOW USAGE
"U"
MEASUREMENT
6.1 Description
The GTFM has a gas flow accumulator, which can be used to display total gas
usage. This function allows the user to measure the total cubic ft. or liters of gas
used from the last time that the accumulator was reset. The maximum volume
displayed is 999 cubic ft. If the usage exceeds this value the accumulator will be
reset to 0 and will count up from zero as the usage increases.
NOTE: WHEN GTFM IS EMPLOYED TO MEASURE METRIC VOLUME, THE
DISPLAYED USAGE NUMBER MUST BE MULTIPLIED BY TEN (10) TO
OBTAIN ACCURATE READING.
6.2 Setup
The accumulated usage value is displayed by consecutively pressing the "MODE"
switch to the up ( "SET") position consecutively until the "U" parameter is displayed.
The value can be reset to zero by pressing the "MODE" key down to the "PGM"
position.
NOTE: THE GTFM PROVIDES A REASONABLE ESTIMATE OF SHIELDING GAS
USAGE. HOWEVER, THIS NUMBER CANNOT BE CONSIDERED TO BE
ABSOLUTE SINCE THE GTFM DOES NOT MEASURE OR MONITOR OTHER
VARIABLES, WHICH MAY HAVE AN EFFECT ON GAS USAGE, SUCH AS
PRESSURE AND TEMPERATURE.
